Your sister is 14 yrs old. your brother is 10 yrs less than twice your sisters age. your cousin is half ur brothers age. write and evaluate an expression to find your cousins age.

Hello!

Let's write this as an equation below.

c= 1/2(2(14)-10)

Let's solve below.

c= 1/2(28-10)

c=1/2(18)

c=9

Therefore, your cousin is 9 years old.

I hope this helps!
